The heavy manufacturing industry is a significant user of water in Australia. Key areas of water use include:

  • Plant and equipment cooling
  • Product cleaning and preparation
  • The application of paint and dyes
  • Product cooling
  • Equipment and site wash down

Generally speaking, there are three main areas for water savings* in industry:

  • Identifying and eliminating wastage (such as leaks) and inefficient processes (such as continual spray devices on stop-start production lines). This may be the most low cost area for water savings, as it involves minimal capital outlay. Savings can be made through implementing procedural changes, such as cleaning plant areas with brooms rather than water.
  • Changing processes and plant machinery. A retrofit of key plant equipment may increase efficiency. Alternatively, upgrades to more efficient models can be factored in to planned maintenance and replacement schedules.
  • Reusing wastewater. As well as saving on mains water, this option may improve the reliability of supply.
